本文描述了加州州立大学两种独特的储热系统:一种用于加热，另一种用于冷却。低温储水箱可提供约36000吨小时的冷冻水。高温储存系统为校园供暖提供150华氏度（66摄氏度）的水。这种解决方案——低温冷冻水储存、中温加热水储存和热泵——特别有趣，因为南加州的高电价。 本文介绍了安装该系统的原因、安装过程以及安装后的性能。特别强调了该系统满足南加州地区特有的环境问题的能力。单位:双引文:研讨会，ASHRAE交易，1998年，第104卷，pt。1A，旧金山

This paper describes the scenario that led to two unique thermal storage systems at a California state university: one for heating and one for cooling. The low-temperature water storage tank provides about 36,000 ton-hours of chilled water. The high-temperature storage system provides 150°F (66°C) water for campus heating. The solution--low-temperature chilled water storage, medium-temperature heating water storage, and heat pump--is particularly interesting because of the high electrical rates in Southern California. This paper provides background on why the system was installed, its installation, and its performance since installation. Particular emphasis is placed on the ability of the system to meet environmental concerns unique to the Southern California region.Units: Dual
